ToraZZ whom it may concern Be it known that I, EDWARD W. HAKE, a citizen of the United States, residing at Cim einnati, inthe county of Hamilton and `State of Ohio, have invented certain new` and use-` ful Improvements in leating-` Stoves, `of which the following is a specification.

It is the object of my invention tofprovide a heating stove with novel means` for in creasing the heat-radiating surfaces; further to provide a heating stovelwith novel means for causing circulation of air thereabout and therethrough; further- ,to provide a novel arrangement of heat-radiating flues; and the invention `will be further readily understood Yfrom the following ldescription, and claims, and from the drawings, in which latter: i i

Figure 1 is a central vertical cross-section of my improved device, taken on a line corresponding to the linelf-l of Fig. 2, and showing the dome partly in side elevation. Fig. 2 is a central vertical cross-section of the same, taken on a line corresponding to the line 2-2 of Fig.;1. Fig. 3 is a rear elevation of my improved deviceiwith the upper part `of the stove broken away and the rear plate which forms therear wall of the rear. flue removed. Fig. 4 is a horizontal cross-section of my improved device,l taken on a line corresponding to the line 4-4 of Fig. 3. Fig. 5 is `a horizontal crosssection of my improved device, taken on a line corresponding tothe irregular line` 5-.5 of Fig. 1. Fig. 6 is a vertical `cross-section, taken on a line corresponding to the irregular line 6-6 of Fig. 1. Fig. 7 is` a side ele. vation of thelower portioniof` thestove partly broken away; and, Fig.8 is a sectional detail on the line 8-8 of Fig.` 3. 11 representsithe tire-pot, 12 thegrate, 13 the ash-pit, 14 the fuel-reservoir, which may be closed at its top by a lid l5 and have thereabove a dome 16.` These parts may be of any ordinary or usual construction.

17,18 are `partition-plates, shown at the front and rear of the stove, connecting `the top of the fire-pot and top ofV the ash-pit, and located respectively in` frontand Vrear of the iire-pot, and, with the ash-pit, forming a heat-radiating wall about the lire-pot. At their` side edges these partition-plates connect, respectively at the front and rear of the stove, with the side walls 19, 20 of the stove, doors 21, 22 being located `in said respective side walls between said partitionplates. i

23 is the ash-pit door, the wall24 of the ash-pit in which said door is located, being the only wall of said ash-pit in the present exempliiication of my invention exposed at theoutside of the stove. The other walls of said ash-pit including its bottom wall, and said partition-plates, form the inner wall or body of the lower portion of the stove.

ends ot'l which have communication withthe firing means, exemplified as the fire-pot. There are openings 2G between adjacent lues, and there is an air-space 27 behind the innerwalls of said flues, with which said openings communicate, this air-space being shown between said ilues and the partitionplate 17 and ash-pit 13. These flues are shown at the front of the stove and extend upand down and curve outwardly lengthwise of the flues, (see Fig. 1), and are arranged cross-sectionally in an arc `across the front of the stove, (see Figs. 4 and `5). There is a `further series of flues `2S extending crosswise of the bottom ofthe stove, preferably from front to rear. The flues 28 have openings 29 between them, and there is an,4 air-space 30 between said ilues `and the bottom wall of the ash-pit of the stove, this air-space communicating with the openings 29. AThere is a cross-channel 31 between the adjacent ends ofthe lues 25 `and 2S, for forming communication between said two series of I'lues, and permitting the products of `combu'stionin the fire-pot to pass from the iire-pot`through the series oi' ilues 25, across the cross-channel 31, and into and through the series of bottom fines 28,1rom the rear `ends of which latter the products of combustion are discharged into a rear flue 32, which extends across the back ofthe stove, and the outer wall of which is formed by the removable rear wall 33 olf` the stove, in which latter a pipe-connection 34 may also" be located, this y pipe-connection arranged to be connected with a suitable chimney. There is a clean-outdoor `35 in the wall of said cross-channel. The bottom airspace 30 connects with the airspace 27 between the wall of the ash-pit and the inner upper corner wall 3G of the cross-channel 31, as shown at 37. t u y i 40 is an air-passage located between` the inner wall 41 ofthe rearflue 32 and the pars s 66 There are a series of flues 25, the upper tition-plate 18' and ash-pit 13, and communicates at 42 with the air-space 30. v

Referring to F ig. l, it will be noted that the front, bottom and rear flues form a substantially U-shaped passage for the products of combustion, the upper end of one limb of which communicates with the firing means, and the other limb of which has suitable connection with the chimney adapted to receive the products of combustion. VIt will be further noted that there is a substantially U-shaped heat-radiation space between said flues and the inner stove-body, one limb of which communicates with the air-openings between the front flues, and the other limb of which forms the up-draft heated-air conduit, which is shown extending to substantially the top of the stove at its rear, for drawing the currents of heated air through said heat-radiation space, said currents of heated air being replenished from the cooler air at the front and sides and under the bottom of the stove. The outer wall 44 of the stove, laterally of the ash-pit, preferably at the left side of the stove, is provided with air-openings 45, which communicate with an air-space 46 between said outer wall and the wall of the ash-pit, the said air-space 46 communicating at its bottom with the air-space 30. The.

air-space 46 is preferably separated from the air-passage 40 at the side of said airspace by a wall 4S, the air-passage 40 con necting with the air-space 46 at the bottoms of said air-passage and air-space, for drawing the currents of air through said airspace and air-passage, the said air-passage extending upwardly a substantially greater distance than said air-space and being heated throughout a large portion of the same at both its front and rear walls, whereby the lighter heated air-currents thus established through the air-passage 40 draw the cooler and heavier air at the side of the stove through said air-openings 45 and airspace 46r into and through said air-passage 40. The air-passage 40 preferably continues above the horizontal plane of the lirepot through the upper part of the stove, the outer wall 50 of said passage being provided adjacent its upper end with openings 51, the upper end of the same being provided with a collar 52 for receiving a suitable pipe or lid. 53 is a damper which is shiftable for o-pening'or closing the passage of the hotair through said collar. 54 is a usual direct draft damper for opening or closing the direct draft Hue 55, and 56 is the usual check-V damper for opening or closing direct passage through a usual flue connecting the ash-pit and rear flue. These latter dam- Vpers are of usual construction and not more particularly shown, because well known.

In my improved device, the course of the lproducts of combustion is from the lire-pot down through the upright flues 25, shownV located at the front of the stove andr through the bottom flues 28, and thence up the flue 32. This arrangement of flues has the advantage that the products of combustion, while their heat is the greatest, pass through'and impart the greatest heat to the upright lues 25 shown at the front of theV stove. These flues 25 are exposed at the outside of the stove and as they receive the rst contact by the hot products of combustion, they radiate the greatest amount of heat, projecting the same directly into the room. The products of combustion, con-V tinuing their course, also heat the'lower normally through the bottom openings and Y the space between the bottom lues andthe inside wall-construction of the stove, the

greater volume of the heated air-currents passing through the hot air flue 40, which is heated at both its front and rear walls, which thereby creates a suction which will normally draw the air through the bottom of the front openings, the lower air openings, and also normally draw the air through the side yair-intake 45 and the sidespace 46, and under the bottom of the rearV partition of said side-space and through the bottom air space, and thence through said hot alr flue 40. The heated air in the upper part of the front space 27 will pass through the upper portions of thefront openings and draw its supply selectively from the lower portions of said front openings and the front portions of the bottom openings, depending on the relation of the heat gener ated by the stove to the heat of the atmosphere surrounding thestove. The heat radiated from the partition-plate 17 will also be projected outwardly into the room.

If the stove is located in a room, the

course of the mainV heated air-currents will be upwardly through the main Vpassage 40. The heated air-currents,'when they strike the ceiling, will be deflected toward the wall of the room andrpass downwardly along the lwall and across the iioor, and beredirected throughthe bottom openings of the stove. It has been ascertained that ordinarily the coldest strata of air is located a slight distance above the floor, approximately nine to eighteen inches above the floor. YAt approxi` mately the elevation of thecoldest strata of air, I provide the air-intalre 45, for normally drawing said cold air inwardly about :the lower inner body of the stove and discharging the same in heated condition. The heat imparted by the flues, owing to ;the locations of said flues and the openings and passages provided for the air, will cause the heated air to pass selectively through said passages and said openings for diffusing the heat in a superior manner.

My improved construction presents a maximum radiating surface, against which the air-currents may impinge, and from which the said air-currents may receive radiated heat for utilizing the heat units of the fuel to best advantage.

My improved device utilizes the flues as means for radiating theheat directly into the room, and also as means for heating aircurrents which pass between said iiues and the lower inner body of the stove and are discharged in heated condition into the room. In my improved device further, the heat radiated from the bottom of the bottom flues is directed against a cooler strata of air under said flues passing toward the openings between said fines, whereby excessive heat radiation directed against the floor on which the stove is located is avoided, and the downwardly projected heat diffused and projected laterally and also through the openings between said flues.

In my improved device the fines for the products of combustion radiate heat at all sides thereof against air-currents diffused in the room being `heated as heated aircurrents.

IIaving thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
